Osakazuki Japanese Maple - Acer palmatum 'Osakazuki'
Regular price
$1,450.00
Title
The Ultimate Specimen Tree for Brilliant Fall Color
Acer palmatum 'Osakazuki' delivers the most spectacular fall color of any japanese maple in the world - an intense explosion of crimson-red foliage that holds for several weeks before leaf drop. This prized cultivar, native to Japan, transforms from bright chartreuse leaves in spring to lush green summer foliage, then ignites into a breathtaking scarlet display each autumn. The fall color of Osakazuki resembles a large drinking glass - the name itself references the traditional Japanese sake cup - and it's earned the Royal Horticultural Society's Award of Garden Merit since 1993 for its outstanding reliability and garden performance.
Why You'll Love It
-
Unmatched Fall Color – Osakazuki has one of the brightest red fall colors among all acer palmatum cultivars, producing an intense display that outshines every other japanese maple variety in the landscape
-
Exceptionally Hardy – Osakazuki is best suited for USDA zones 5-8 and tolerates both cold winters and warm summers with remarkable resilience
-
Low Maintenance – Requires minimal pruning and care once established; fertilization is not often needed for Japanese maples, making this a straightforward tree to grow
-
Perfect Size – Osakazuki can reach 10-15 feet tall and wide, making it an ideal small tree for most residential gardens without overwhelming the space
-
Sunburn Resistant – Osakazuki's leaves are firm and larger than other palmatums, which means Osakazuki has less sunburn than other Japanese maples when planted in proper conditions
What Makes It Different
Most japanese maple cultivars either offer modest fall color that fades quickly or require delicate, hands-on care to keep them looking their best. Many red-leafed varieties like 'Bloodgood' Japanese maple or 'Atropurpureum' carry purple-red foliage all summer but can't match the dramatic autumn transformation.
Acer palmatum Osakazuki offers:
-
Award-Winning Pedigree – It received the Royal Horticultural Society's Award in 1993, confirming its status as a garden merit winner with proven performance and reliability across diverse growing conditions
-
Superior Leaf Structure – Unlike laceleaf or dissected cultivars, Osakazuki features broad, 7-lobed palmate leaves that create stronger visual presence at landscape scale and resist wind damage far better
-
Broader Sun Tolerance – Osakazuki thrives in part shade to full sun, performing well in conditions where more delicate maple varieties like 'Emperor One' Japanese maples would scorch and struggle
How To Grow The Osakazuki Japanese Maple Successfully
-
Plant in the Optimal Location Choose a spot with well-draining, moist soil and morning sun with afternoon partial shade protection. The tree prefers rich, moist, slightly acidic, and well-draining soil - amend clay soils with organic matter for best results.
-
Establish a Strong Root System Water consistently during the first growing season. Young trees need moisture but mature trees are drought-tolerant once their roots are well-established. Apply mulch around the base to retain soil moisture and keep roots cool - but keep mulch a few inches away from the trunk to avoid decay. For detailed sizing and care information, you can review our full Osakazuki Japanese maple profile as a reference.
-
Enjoy the Seasonal Display Watch as leaves emerge bright chartreuse in spring, mature into rich green summer foliage, then transform into a spectacular crimson fall display. Osakazuki is known for its intense fall color that holds for several weeks before the leaves drop.

Frequently Asked Questions
How long until I see full fall color? Expect vibrant leaf color by the second or third year after the tree is planted. Even young trees produce noticeable crimson tones - the display intensifies each year as the canopy fills out.
Will it survive hot California summers? Yes. Osakazuki is more heat-tolerant than most japanese maple varieties. Site it where it receives morning sun and afternoon shade, maintain consistent water during summer, and mulch generously to keep roots cool. It can handle full sun in coastal areas where temperatures stay moderate.
How much space does it need? Allow 12-15 feet of clearance from structures and other large trees. The rounded canopy spreads wide at maturity, so give it room to develop its natural vase-shaped form without crowding.
Can I grow it in a container? Yes, Osakazuki can be grown in containers - it even has interest as a bonsai subject - but larger specimens need spacious pots with excellent drainage. Container-grown trees require more frequent watering and winter root protection. Repot every few years as roots expand, and consider pairing with compact flowering standards like the Red Crape Myrtle tree for extended seasonal color on patios and entryways.
What pests should I watch for? Keep an eye out for pests like aphids and scale, which can occasionally occur on Japanese maples. Good air circulation and avoiding waterlogged soil help prevent fungal leaf spots. Healthy, well-sited trees rarely face serious pest pressure, especially when combined with resilient, sun-loving companions such as purple bougainvillea.
Does it need regular pruning? Pruning should be minimized to prevent sap bleeding. Remove only dead or crossing branches during late fall or winter dormancy. The goal is to maintain the tree's natural scaffold structure rather than control size.
Should I fertilize it? Fertilization is not often needed for Japanese maples. A light, balanced feed in early spring is sufficient. Avoid fertilizing in late summer, as this can push tender new growth that's vulnerable to winter damage.
Ready to Transform Your Garden?
Osakazuki Japanese Maple delivers award-winning brilliance - the kind of intense, crimson autumn display that stops neighbors in their tracks and makes your garden the talk of the street, comparable in impact to larger shade selections like Rocky Mountain Glow maple.
Add the Osakazuki to your landscape and experience what the Royal Horticultural Society recognized over three decades ago: this is the most spectacular fall color a japanese maple can offer.

Thousands of Healthy Plants Delivered
Yardwork was so great to work with. First they had the Swan Hill olive trees that we had been searching for, we had contacted several other nurseries without any luck previously. Then they answered all of our questions in a timely matter prior to ordering and finally delivered within a few days of placing it. Their staff is incredibly knowledgeable; they delivered and planted our trees with expertise to ensure that they would do well in our yard. We would definitely work with them again for future projects.
